Membuat Animasi Orang Berjalan Memakai Thread Di Java 2D

Halo gan! Ini ialah project ane dulu waktu masih kuliah. Kaprikornus tugasnya itu menciptakan animasi bergerak. Nah, dasar dari sebuah animasi itu ialah thread.

Apa itu thread? Nanti aku akan jelaskan di postingan yang akan datang.

Konsepnya bekerjsama sederhana, jadi ada sebuah thread yang mengatur jalannya animasi. Kita sanggup mengatur millisecond dikala thread berjalan.

Inti dari project aku ini yaitu ada dua buat gambar/posisi orang, lalu bergerak dan berubah posisi secara bergantian.

Oke pribadi lihat saja source codenya, bebas untuk di utak-atik :
